I have tried all types of toys from buttplugs, vibes, dildos, anal toys and the strapon.
I found the best was a penis type of dildo. Not because I want a cock in my ass, I enjoy the feeling of the ridges, veins,head popping in and out of my ass. Smooth anal toys were boring.

I've used. A fleshlight, anal plug, anal beads among other things. The fleshlights semi fun when the girlfriends not up to it. But not as quick as my hand. And the anal beads are awesome, especially in comparison to the plug. I get a fullness and a kind of ribbing feeling I think I could say and shewill play with them as she's blowing me slowly in and out on the deep side. And slowly pulling out when im cumming during sex and it'll make my orgasm feel longer and more intense.
